Summary
The Enniskillen Environmental Association (EEA) comprising residents who live in the vicinity of the
proposed Clarington Transformer Station site are concerned about the undertaking outlined in the Draft
Environmental Study Report (ESR) (Hydro One, 2012). The EEA is particularly concerned about impacts
of the undertaking on the quality of their drinking water supply. Following review of the Clarington
Transformer Station Class Environmental Assessment Draft Environmental Study Report (Hydro One,
2012) and related documents, it is our expert opinion that insufficient site specific hydrogeological
characterization has been conducted to ensure the safeguarding of groundwater: 1) used by residents in
the area for domestic supply from private wells; and 2) for the protection of “hydrologically sensitive
features”.
The development of a scientifically defensible site conceptual model (SCM) for the proposed site as
discussed in Hydro One (2012) and Stantec (2013) is inadequate. The SCM needs to be developed to a
level of detail that is commensurate to the problem being addressed. There needs to be greater
description and investigation of: the site hydrology and geology; contamination sources and properties;
release mechanisms and rates; environmental fate and transport processes; possible receptors; and any
other elements that will help to define and resolve issues related to the undertaking (USEPA, 1993).
We recommend that further hydrogeological study and SCM development is completed prior to decision
making regarding appropriate siting of the transformer station in order to ensure that “hydrologically
sensitive features” and water resources used by residents for domestic supply are not adversely
impacted by the development. From a hydrogeological and contaminant transport perspective we
support EEA’s request for a higher level of assessment (bump up to an Individual EA) to allow the
opportunity for the development of a scientifically defensible SCM.
According to the MSDS, this highly refined mineral oil has a specific gravity of 0.82 to 0.89 and a
viscosity of 8 to 9 centistokes (cSt) at 40oC. Chemical properties are required to determine
subsurface geochemical interactions and any unforeseen issues that could occur in the event of
a leak or release based on the site specific flow system and geochemical properties. This
requires further field investigation to develop the SCM. Mathematical modeling can be used to
help elucidate and refine the SCM. There is also a lack of appropriate information available, at
least in Hydro One (2012) and Stantec (2013), about any environmental health hazards
associated with this undertaking. If contaminants such as mineral oil enter the groundwater
system they can cause strong biogeochemical reactions that will change the groundwater quality
by reducing the redox conditions and releasing natural metals such and iron and manganese or
other constituents that can render well water unusable. Thus, the oil itself need not be the
actual contaminant that does the main harm. Certain contaminants appear to be harmless but
the secondary effects can be the main impacts. This needs to be investigated during
development of the SCM.
Hydro One (2012) states “the station will be fully equipped with spill containment and oil/water
separation facilities. In the event of equipment failure, oily water will not escape from the site”
and later “Hydro One is confident that, in the event of equipment failure, mineral oil will not
escape from the site.” What is the uncertainty related to these statements? What is the risk of
failure? More evidence that “oily water” will not be released to the environment is required in
the SCM. A project site should be chosen where the groundwater resources will be the least
affected should a leak or release occur. For potential environmental releases in section 7, Hydro
One (2012) also states:
In addition, the station will be situated on land with a deep overburden of glacial till which
has very low permeability. In the rare event that oil did escape the containment system, the
response time by Hydro One would allow for cleanup of the oil in advance of any movement.
Consequently, no effects to the groundwater hydrology of the study area are anticipated.
Further, the monitoring well installed at the site will be maintained and monitored regularly
for groundwater depth and quality.
12
Considering our discussion herein of the lack of hydrogeological characterization (e.g., measured
hydraulic conductivity; interpretation of the groundwater flow system) contributing to the
development of a SCM, it is our opinion that the above statement cannot be concluded.
Quantitative assessment is required.
6) Extent or connectivity of the shallow flow system has not been investigated in a fulsome
manner.
To determine any possible impacts of the undertaking on the private wells used by nearby
residents, detailed information about the physical flow system is critical for SCM development.
From shallow geotechnical drilling, Hydro One (2012) and Stantec (2013) both describe and
illustrate using cross sections “sand lenses” present in the top 15 m below ground surface that
are “about 3.2 m thick” (Hydro One, 2012) and up to 5.8 m thick (Stantec, 2013). Hydro One
(2012) notes “it is expected that these sand lenses whose continuity is unknown, may be the
water source for the shallow wells in the area and seepage areas noted by local residents.”
Stantec (2013) states that “based on the available data, a significant, continuous aquifer was not
noted within the local study area” and “the aquifer material is interpreted as an intermittent
sand and gravel lens up to 5.8 m thick, with no significant continuous aquifer noted across the
project area” and “nearby private wells are installed within these intermittent sand lenses, as
encountered at various depths”. A geological assessment of the origin of these sand bodies is
required in the SCM.
In our opinion, insufficient site specific data has been collected to determine the flow system
interconnectivity. As illustrated in orange in the regional cross-section presented in Appendix B
the Oak Ridges (or equivalent) layer may be present at the site which lies between Conc. Rd. 8
and Conc. Rd. 7. Hydraulic characterization for the SCM as outlined in (3) is a data gap. It is
needed to determine the flow properties and interconnectivity of the shallow system in order to
evaluate any impacts of the proposed undertaking on neighboring water supply and on
“hydrologically sensitive features”. Connections of the shallow system to the deeper aquifer
(i.e., Thorncliffe Formation) should also been investigated, which will require the installation of
multilevel or nested monitoring wells to determine vertical gradients and to obtain groundwater
samples for analysis.
7) A scientifically defensible investigation of “hydrologically sensitive features” has not been
conducted.
According to the Oak Ridges Moraine Conservation Act, 2001 “hydrologically sensitive features”
include “seepage areas and springs”, O. Reg. 140/02, s. 26 (1). Wetlands and streams are also
sensitive features. The regulation continues to state:
(3) An application for development or site alteration with respect to land within the
minimum area of influence that relates to a hydrologically sensitive feature, but outside the
13
hydrologically sensitive feature itself and the related minimum vegetation protection zone,
shall be accompanied by a hydrological evaluation under subsection (4).
(4) A hydrological evaluation shall,
(a) demonstrate that the development or site alteration will have no adverse effects on
the hydrologically sensitive feature or on the related hydrological functions; …
Hydro One (2012) states that CLOCA (2011) mapping identifies no potential groundwater
discharge areas within the project area. Yet, as noted in Stantec (2013) there is anecdotal
evidence of seepage areas at various locations on the proposed site. Additionally, the hydraulic
head measured for monitoring well BH11-12 is above the ground surface (it is a flowing artesian
well) as reported in Stantec (2013). This well is situated adjacent to Wetland Area 1 (see Figure 9
in Stantec, 2013). The relation between the existence of the wetland and nearby artesian
conditions and relationships to groundwater seepage has not been evaluated. A thorough
understanding of the discharge processes across the entire site with conclusions drawn from
detailed hydrogeological characterization is required to ensure that the “development or site
alteration will have no adverse effects on the hydrologically sensitive feature or on the related
hydrological functions”. This needs to be described using the SCM.
The hydrogeological characterization conducted thus far, in our opinion, has not sufficiently
investigated seepage/discharge areas in a scientifically defensible manner. Understanding local
groundwater discharge in headwater areas is critically important to maintain downstream
hydrology and biodiversity (e.g., Meyer et al., 2007; Winter, 2007). From detailed
hydrogeological investigations, Gerber and Howard (2002) describe various groundwater
discharge mechanisms for the Oak Ridges Moraine in the nearby Duffins Creek watershed west
of Oshawa. They observed that about 24% of the total system recharge emerges above the 275
m above mean sea level (amsl) contour while the rest: “(i) moves in the Upper aquifer and
discharges to headwaters immediately below 275 m amsl; (ii) moves within the Upper aquifer
and enters streams situated within the South Slope physiographic region, well to the south of
the headwater area; (iii) moves within the Upper aquifer to discharge as springs along deep river
valleys where the river has eroded into or beneath the Northern [i.e., Newmarket] till; (iv)
enters the Middle and Lower aquifers and re-emerges as groundwater discharge to streams in
the southern part of the study area; and (v) moves within all aquifers to discharge at Lake
Ontario.”
Hydro One (2012) states that tributaries of headwater streams at the site were at times dry and
it is assumed that “the tributaries are minimally, if at all, supported by groundwater.” This is a
difficult conclusion to draw without detailed (continuous) measurements of stream stage/flow
rate and adjacent groundwater hydraulic heads. Any groundwater-surface water interactions
with the streams, wetland areas and seepage areas need quantitative evaluation using, for
example, appropriate well infrastructure to obtain samples for water parameter analysis (e.g.,
environmental isotopes). This quantitative evaluation needs to be used during the development
of the SCM.
14
8) The determination of “aquifer vulnerability” (high or low) has been based on regional scale
mapping.
Hydro One (2012) states “the sandy silt till retards water penetration and is referred to as an
aquitard. This supports the Gartner Lee (1978) findings stated above and CLOCA (2011) findings
which indicate that the lands upon which the project area is located are not considered an area
of Significant Groundwater Recharge, nor within an Intake Protection Zone (CLOCA, 2011).”
Similarly, Stantec (2013) describes that the aquifer is low vulnerability as indicated in CLOCA
(2012). As discussed previously in (4), there is no site-specific evidence to support that the sandy
silt till “retards water penetration”.
Hydro One (2012) states “although portions of the surrounding area are categorized by CLOCA
as having medium or high aquifer vulnerability, the entirety of the land within the proposed
station is considered to have low aquifer vulnerability.” The evaluation of Significant
Groundwater Recharge areas and the evaluation of aquifer vulnerability have been based on
regional scale mapping (i.e., Aquifer Vulnerability Index for vulnerability assessment) and a
refined interpretation should be conducted using site specific data for the development of the
SCM. A detailed aquifer vulnerability study, based on site specific infiltration, conductivity data
and hydrostratigraphy is more appropriate (e.g, Focazio et al., 2002) for this undertaking.
9) The hydrogeological impacts of the proposed underground drainage system, construction
dewatering and new site grading have not been evaluated quantitatively.
Due to near-surface groundwater, dewatering during construction is anticipated and a drainage
system for the operation phase is planned (Hydro One, 2012). An evaluation and development
of the SCM is required to determine: will these site modifications affect groundwater recharge
and discharge (i.e., local seeps, springs, wetlands, and streams)? How will the grading of the site
(i.e., up to 6 m of excavation near well BH11-12 where artesian conditions are observed;
Stantec, 2013) impact the water table and hence groundwater recharge and discharge
processes? Stantec (2013) states that groundwater seepage will likely result from excavation in
the eastern portion of the site. Mathematical groundwater modeling of the site pre- and post-
development could contribute to the SCM.
10) The proposed groundwater monitoring program is inadequate for both spatial and temporal
frequency.
Water level measurements of the currently installed four (shallow) monitoring wells, to our
knowledge, have only been taken on a few discrete events. We are unaware of water sample
results if they have been analyzed. The monitoring program presented in Stantec (2013) is an
adequate first step, but more detailed monitoring is required to obtain a fulsome picture of
water flow and any contaminant transport issues for the SCM. Quarterly water level monitoring
was recommended (Stantec, 2013). In our opinion, continuously logging pressure transducers
15
should be installed in new multilevel or nested monitoring well infrastructure prior to site
development to help determine more about the flow system and connections to the surface
including recharge and discharge processes for the SCM. This is common practice in research
and industry.
Semi-annual (spring and fall) water sampling was recommended for general chemistry analysis
(Stantec, 2013). More frequent, as well as additional analytes including environmental isotopes
(to help resolve recharge and discharge processes) would be beneficial. Spatial and temporal
variations of groundwater sample results can be significant. Three discrete monitoring events of
private wells (Stantec, 2013) is a good start, but they: 1) will not provide adequate data to
determine if the water levels of residents are being affected since there is no understanding of
seasonal processes and recharge events; and 2) will not provide a detailed understanding of
water quality due to any seasonal variations. More detailed is required for the SCM.
11) An appropriate evaluation of uncertainty has not been conducted.
First, detailed hydrogeological characterization must be conducted to develop the SCM. An
assessment of the uncertainty of measured and derived parameters that define the flow and
geochemical systems presented in the SCM must be described.
16
3.0 Conclusions and Recommendations
It is our opinion that prior to development of the transformer station a comprehensive field based
assessment must be carried out to obtain a clearer understanding of the hydrogeological and
geochemical implications of the proposed undertaking. The data for development of a scientifically
defensible SCM is currently inadequate in Hydro One (2012) and Stantec (2013). See, as an example, the
detailed investigation conducted by Gerber et al. (2001) west of the proposed Clarington site to obtain
an extensive understanding of the flow system. We recommend that further hydrogeological study and
SCM development is completed prior to decision making regarding appropriate siting of the transformer
station in order to ensure that “hydrologically sensitive features” and water resources used by residents
for domestic supply are not adversely affected by the development. From a hydrogeological and
contaminant transport perspective we support EEA’s request for a higher level of assessment (bump up
to an Individual EA). We recommend that further study could include (but should not necessarily be
limited to) the following to contribute to the development of the SCM:
1) Determine the basic, essential properties of the flow system (e.g., hydraulic conductivity,
hydraulic gradient, effective porosity, etc.).
2) Install numerous nested or multilevel monitoring wells for this purpose. Further analysis is
required to determine the appropriate locations, depths and number of monitoring wells.
3) Evaluate with site specific investigation the inputs and outputs to the groundwater system (e.g.,
recharge and discharge areas; pumping effects) to elucidate groundwater-surface water
interactions.
4) Determine the age of the groundwater.
5) Improve the conceptual model of the hydrostratigraphy and flow system. This requires drilling,
hydraulic characterization, and installation and monitoring of multilevel or nested monitoring
wells. An investigation of till flow properties and characteristics is required.
6) Collect detailed (i.e., continuous) water level measurements and frequent (e.g., at least
monthly) water samples for analysis.
7) Evaluate the impact of the proposed shallow subsurface water collection on the “hydrologically
sensitive features” and overall flow system. Processed-based mathematical groundwater flow
models can be used to elucidate the SCM.
8) Quantitatively evaluate the aquifer vulnerability using field-measured parameters.
17
9) Evaluate the transport and geochemical effects of a potential discharge of the transformer oil to
the subsurface in the event of a leakage or spill. Process-based solute transport models can be
used for this purpose. The likelihood of a release of transformer oil to reach the water table and
domestic well receptors should be evaluated. Information about the source of potential
contamination (i.e., solubility, concentration, volume, etc. of the transformer oil) is required.
Performing a detailed hydrogeological assessment of any impacts of development (and choosing the
most appropriate site based on the findings) prior to construction can ultimately be less expensive than
remediation post-contamination should a leak or release to the environment occur. The above
recommendations are minimum components for the development of a SCM. Should the proponents
desire to pursue the undertaking at the currently proposed Clarington site, it is our opinion that detailed
hydrogeological and geochemical study should be conducted to provide scientifically defendable
evidence that the groundwater resources (quality and quantity) will not be adversely impacted by the
proposed development. This project cannot move forward responsibly without a more thorough
investigation of any hydrogeological impacts of the development on “hydrologically sensitive features”
and to private well users in the area. Data gaps must be filled. The SCM needs to be developed to a level
of detail that is commensurate to the problem being addressed. There needs to be greater description
and investigation of: the site hydrology and geology; contamination sources and properties; release
mechanisms and rates; environmental fate and transport processes; possible receptors; and any other
elements that will help to define and resolve issues related to the undertaking (USEPA, 1993). It is
essential to use scientific evidence to protect in the most comprehensive way human and environmental
health.

Summary Statement My research primarily concerns intensive field studies at carefully selected industrial sites where organic contaminants have occurred in the groundwater for a long time (i.e. decades). I apply new methods of data acquisition and improved versions of existing methods, both at exceptionally detailed spatial scales, to determine the contaminant distributions in ways best suited to identify and quantify the dominant processes of transport and fate responsible for the contaminant distributions. My main contributions to groundwater science include: 1) development and field proof of innovative methods, 2) understanding of processes most relevant to the critical scales of geologic and chemical heterogeneity, and 3) advancement of conceptual models in contaminant hydrogeology. I began my PhD research concerning contaminant hydrogeology in 1992 and completed the PhD degree in 1996. My research focus continues to evolve. The early years were focused mostly on fractured clayey aquitards, then much of my attention was directed at heterogeneous sandy aquifers and in the last decade my work has mostly concerned fractured sedimentary rock. I am strongly collaborative in ways aimed at improving the scope and rigor of my field studies and enhancements in data interpretation using mathematical models. I have authored/ co-authored 55 papers in refereed journals and many other papers. For my published works, The Google Scholar citation index reports a total of 979 citations, of which 682 are in 2007 and more recent. I have arranged the five most important contributions below according to this evolution of emphasis in my research. Current Research Focus Contaminant hydrogeology with emphasis on industrial organic contaminants, field studies and remediation in diverse geologic domains including fractured sedimentary rock, clayey aquitards and sandy aquifers. Development of the Discrete Fracture Network Approach for investigating contamination in fractured rock. Current Responsibilities Conduct research in the field of contaminant hydrogeology, secure and manage research funds from external sources; supervise graduate students, post-doctoral fellows and research associates; project management including Associate Director of University Consortium for Field Focused Groundwater Contamination Research; manage an organic contaminant analysis laboratory and co-manage field investigation facilities; teach graduate course in groundwater contaminant in fractured media and occasionally an undergraduate course (physical hydrogeology); employ undergraduate co-op research assistants.

Research Focus
My research focuses on groundwater resources, specifically flow and contaminant transport with an interest in sensitive fractured bedrock aquifers. My approach includes coupling field research and mathematical modeling to characterize and study vulnerable aquifers with the intent to technically inform policy to protect water resources. During past research I have focused on rural (agricultural) and climate change impacts on groundwater quality and quantity. My other areas of research interest include: source water protection; innovative field characterization techniques; appropriate potable water technologies for marginalized communities; and fostering engineering and technological input into public discourse.
